VALVE AND THE LRE.

Application ala July 15,

Be it known that I EDWARD E. Hour, a

States, residing at. Chicago, in the county of Cook and State of Illinois, have invented certain lnew and useful Improvements in Valvesand the like, of which the following is a specification.

This invention has to do particularly with certain improvements in the construction of valves and the like. 'Ihe invention has reference particularly to improvements in construction of such valves as water faucets, etc., but it will presently appear that the features of the invention and their usefulness are not limited to water valves or valves for any'other particular use. Nevertheless, owing to the fact that the construction herein disclosed is very well adapted for use in water valves or faucets, I have Iillustrated the resent invention as being particularly app led to this Yclass of use. ,It will be understood, however, that in so illustratin and describing the invention, I do not inten to limit the same to use in water faucets and the like except as" Il may do so in the claims. One of the objects of the invention is to provide a valve lof such construction and arrangement that a very perfect seal may be secured between'the valve and its seat so as to absolutely shut 0E the fluid flow when the valve is closed. Another object in this connection is to secure this result b means of a. metal to metal contact, botht e valve and seat beingv made of'metal.- Owing to this fact, the. useful life of the valve will be greatly increased, since the wear will 'be argely reduced as compared to those valves in which one of ,the elements is of composition. v

Another object of the invention vis to provide an arrangement such that when arelatively small pressure is exerted on the handle, a pressure will be exerted between the valve and its seat, sufficient to eectively 4close the o ening in an absolutely tight manner. lIn t is connection, a further object is to accomplish this result by the use of a tapered valve working into a tapered seat.

A still further object ofthe invention is to rovide an arrangement such that the valve itself shall have a relatively thin and flexible contacting edge to take into the seat, both the `seat and the valve being tapered or cone shaped, so that the aforementioned wedging action is secured in conjunction with the 1922. 'serial No. 575,424, i

feature of a relatively flexible contacting edge 1n order to insure a tight contact all the way around the valve notwithstanding slight irregularities in manufacture, vand also notwithstanding the fact that both theV valve .and seat are made of metal. A

A further object of the invention is to prov1 de a construction such that the valve plug will be removable with respect to the stem,

so that the plug itself may be easily removedor replaced without having to replace unnecessary parts.

A further object of the invention is to provide an arrangement such that the valve plug will always be accurately guided in its movements with respect to the seat, so that its contacting edgewill alwaysA take properly into the seat in wedging fashion, and without the possibility of jamming the lower edge ofthe'valve' plug against parts other than the valve seat itself.

Other objects of the invention will appear. from a detailed description of the same, which consists in the features of construc-4 tion and combinations of parts hereinafter described and claimed.

InI the drawing:

Figure l shows a side elevation of a water 4, looking in the direction of the arrows;

Figtshows a plan view corresponding to Fig. 3; A

Fig 5 shows a side elevation of the brass block after the same has been proliled;

Fig. 6 shows a plan view corresponding to Fig. 5;

Fig. 7 shows a vertical section taken on the line 7-7 of Fig. 6, looking in the direction of the arrows;

Fig. 8 shows a vertical section through the Monel metal block; and' Fig. 9 shows a vertical section through the brass block and Monel metal block after they have been assembled.

In the yparticular construction of valve illustrated in the drawing, there is provided a vertical stem 10 for attachment to a water pipe, the upper portion 1.1 of the same being is adjustable with respect to the stem, soA

rectangular or non-circular for insertion into the hole of the marble or composition support. 'llhis valve or faucet is also provided with a circular Bange 12 adapted to rest on the top surface of the marble or composition block. llt is also provided with an outwardly extending spout 13 through which the water is dischar d.

intermediate between the water supply connectionl() and the spout 13 is a horizontal partition 14 which is provided with a central passage 15 which tapers from top to bottom,I so that as the plug is forced into it a wedging action takes place. Upon opening the passage or port 15 the water is allowed to pass through .the spout.

Directly above the partition 14C is a vertical stem 16 on the upper end of which is mounted the handle 17 by means of which it may be turned. rllhe stem 16 has a threaded enlarged portion 18 which works in the vertical threaded chamber 19, so that as the handle 1'? is turned the stem 16 is raised or is orced downwards. A washer 20 is provided around the stem =16 and at the upper end of the threaded chamber. A .suitable backing material 21 is placed around the stem and above the washer, said backing material being clamped tightly around the stem 16 by a cap screw 22 which-threads onto the outsideface oit the structure.

Avalve plug 23 is connected to the lower 'end of the stem 16 and is raisedand lowered thereby from and towards the valve seat 15. 'llhis plug 23 has on its lower end a circular tapered flange 24, the dange being formed by a central counter bore 25 which reaches up into the vlower end of the plug.V The lower edge 26 of this flange is relatively thin, so that as it is forced into the tapered valve seat 15 a strong wedging action takes place to provide a very tight seal. The

lower portion of the lange is preferably made suiciently thin or flexible to allow a slight amount of deflection to take place when wedged into the tapered seat 15, so that the lower sealing edge ot the plug will come into iirm-close engagement with the seat all the way .around the same..

llt is also preferred that the taper of the seat 15 be made at a slightly greater angle than the ta er of the flange 2l so as to insure that t e primary contact between the llange and the seat shall always be at the lower edge of the dange.

'llhe plug 23 is 'connected to the lower end ot the stem 16 in any convenient manner, or in some cases is made rigid or integral with respect thereto. I'llhe preferred construction, however, is one in which the plug that the plug will always seat accurately without regard to the exact alignment oittl-re stem and the valve seat l5. A further pi'r'efrecalca erence is that the plug be' removable with respect to the stem, so that new plugs can be set into the device from time to time it needed. Y

'llhe arrangement shown in the drawing complies with both of the above mentioned preferences. rlhe lug in this'instance has its upper portion s otted as shown at 27, the slot being undercut as Shown at 28 and 29. 'llhe lower portion of the stem 16 is grooved as shown at 30 to provide a flange 31 whichv may reach into the undercut portions 28 and 29 of the slot 27. ln' this way the plug is connected to the stem, so that the plug and stem can turn with respect to each other, and the plug may move slightly back and forth with respect to the stem, and the plug may be easily removed from the stem when the stem and plug have been taken out of the faucet, such removal being eected by moving the plug sidewise with respect to the stem.

. rllhe Huid pressure is normally exerted from beneath and against the lower portion of the plug. When the plug is raised from the seat and the water or other fluid or air .is Howing past the plug, there is a natural distorting tendency which tends to torce the plug to one side or the other and thus tends to destroy the alignment of the plug with respect tothe seat. rll`histendency is.

greatly aggravated in the case ot openings of considerable size, and in the case oi water or duid pressures of substantial amount. Furthermore, in those cases in which the plug is vmovable with respect to the stem, the

stem itself cannot be relied upon to substantially guide the plug in its movements. `ll have, therefore, provided an arrangement such that the 'plug is guided in its movements in order to retain it at all times in substantial alignment with res ect to the valve seat and opening 15. lin t e construction illustrated, this means takes the form f of a circular flange 32 reaching down into thebody of the device and surrounding the lower portion of they stem 16 as well as the the dange 2t of the plug it is possible to esl tablish thevidesired guiding co-operation between the flange 32 and the upper portion ol the plugI while at the same time allowing a very su stantial clearance between the lower edge of the dange and the chamber within A l"as brass.

- reoaioa which the plug works so as to allow for an ample flow of water or other Huid.

rlhe plug itself may be made of any suitable material, but it is desirable to use a material having substantial durability and also having a sufficient flexibility to establish the desired (so-operation between the lower edge of the lia-nge 24 and the valve seat.l Such a material is, for example, Monel metal or other similar alloy, but except as called for in the claims, l do not limit m self to the use of this metal. This metal 1s, however, very hard to work, and, therefore, l prefer to support the flange portion of the plug, when made of Monel metal or the like, on a block of some other composition such l, therefore, illustrate the upper portion of the plug as comprising .a brass block 33. rlhe :flange 24: of the plug is formed as a continuation of a relatively thin block or washer 34 having upstanding therefrom a neck 35 which is centrally recessed at 36, so that its upper edge 37 is relatively thin.

The brass block 33 is initially drilled to provide an upper relatively large passage 38 in conjunction with a lower smaller passage 39, a tapered seat 40 being established at the point where these passa es come tovether. After the brass block has een drilled in this manner, it is proiiled in the manner shown in Figs. 5 and 6 so as to establish a transverse slot 41 reaching across the block, at least as far as the central ortion thereof,

the sides of said slot Lil being undercut as shown at 42 and 43. rlhe Monel metal flange portion then has its lip 35 set up into the smaller opening 39 of the brass block and the'upper edge 37 is then s un out against the taper 40 ot thel brass lock as shown in Fig. 9, so that the two elements of the block are rigidly and permanently fastened together.

l wish to state that although l have herein disclosed and described in detail a particular construction of plug, a portion of which is made of Monel metal, nevertheless, l do not claim this construction of plug in this application, except in some cases in combination, since l have also disclosed this general form and construction of plug in a copending application :tor Letters Fatent of the United States executed by me of even date herewith.

While l have herein shown and described only a single embodiment of the features of m present invention, still l do not limit myse f to the same except as l may do so in the claims. i
